WRENCH.

Specification of Letters Patent.

Application led. December 6, 1913.

Patented June 9, 1914.

Serial No. 805,087.

To all whom it may concern Be it known that we, LEONARD C. Mosn and ANTHONY OLIVER PONS, citizens of the United States, residing at Covington, in the parish of St. Tammany and State of Louisiana, have invented new and useful Improvements-in lrenches, of which the following is a specification.

The present invention relates to improvements in wrenches, and has for its Object to provide a comparatively simple and ineX- pensive device of this character in which gripping jaws may be readily clamped in engaging position, and one in which the jaws will be moved alternately to open position for engagement with a nut or bolt.

With the above recited objects in view, and others which will appear as the nature of the invention is more fully understood, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and fall ing within the scope of the appended claims. j

In the drawing: Figure 1 is a perspective view of a wrench constructed in accordance with the present invention, Fig. 2 is a sectional elevation of the wrench, the section being taken centrally and longitudinally thereof and illustrating the compression member or sleeve acting upon the rear or tail portion of the jaw beyond its pivot for swinging the jaw to an open position, and Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2, and Fig. 4 is a perspective view of a modified form of the sleeve.

Referring now to the drawing in detail, 1 designates the body or shank of the wrench which has one of its ends terminating in a fixed jaw 2. The jaw, at its end, is providedl with a longitudinally extending depression. 3, and upon its inner face at a suitable distance from its ends with a transversely arranged depression 4. The shank 1 terminates in a reduced portion 5 preferably of a rectangular form in cross section and designed for engagement by a brace, handle or other operating member. The shank 1 is formed with a longitudinally arranged depression 6 upon its end opposite to that formed with the gripping .jaw 2, ythe said depression entering the outer face of the shank and the lower wall of said depression is inclined from the end of the said shank toward the transverse wall provided by the depression, as indicated by the numeral 7.

Pivoted, as at 8, between the walls formed,`

by the depression 6 is the movable or swinging jaw 9 which is provided with a transverse depression 10 and a longitudinally V-shaped `depression 11, the said depressions adapted to register with the depressions 3 and 4, when the jaw 9 is swung upon the jaw 2. The pivot of the jaw 9 is arranged near the end of the shank 1, and the said jaw to the rear of its pivot is provided with what I term a reduced tail 12. The jaw 9 is of a width equaling the jaw 2 and the distance between the walls provided by the depression 3 is less than the width or thickness of the jaws, so that the tail 12 is reduced, providing the jaw 9 with shoulders 13 which abut with the shoulders formed on the ends of the walls at the opposite sides of the depression 6. The lower wall of the tail is inclined from its juncture with the jaw proper to the end of said tail, so that the jaw 9 may be swung a comparatively great distance away from the jaw 2. rlhe outer face of the tail 12, from its juncture with the jaw proper is enlarged to provide a declivous surface 14, the said inclined enlargement sloping from the end of the tail to the juncture of the tail with the jaw proper.

IThe numerall 15 designates a sleeve or compression member which is arranged upon both of the jaws, the said member having its outer face, opposite the outer face of the jaw 9 beveled inwardly toward its bore, as indicated by the numeral 16, the said beveled portion serving as an engaging surface for the jaw when the latter is swung to its outer position. The shank 1, to the rear of its depression 6 is provided with shoulders 17 which are adapted to contact with and prevent the movement of the sleeve 15 toward Ythe reduced portionof the shank. The jaw 9 is of a greater thickness at its outer end than at its uncture with the tail piece 12, the inclination from the said end being gradual, but suiiicient to prevent the sleeve 15 from being withdrawn in an outward direction from its engagement with the jaws 2 and 9. It will be noted that when the sleeve or compression member 15 is moved toward the ends of the jaws, the'same willforce the jaw 9 toward the jaw 2 and the frictional engagementbetween the said member 15 and the jaw 9, owing to the inclined surface 16, will hold the said jaw 9 at any adjusted position with relation to the jaw 2, and furof the member 15, thesame will travel over the declivous surface 14 upon the outer face of the tail, and thus swing the jaw 9 to an open position.

. In order to reinforce the side walls provided by the depression 6, and also to retain the pivot 8 against accidental removal, we have formed this portion of the wrench, forward of the shank 1, with a continuous depression A within which is received a reinforcing band B. The band lies flush with both the sides and the faces of this portion of the wrench, so as not to interfere with the movement of the compression member 15. rlhe upper portion of the tail of the movable or swinging jaw 9 is provided with a depression C so that the member of the band arranged across the said tail will not contact with the tail. The band also serves as a means for forcing the side walls provided by the depression 6 into frictional engagement with the sides of the tail 12.

In Fig. 4 we have illustrated a form of sleeve which may be employed. rIhis sleeve, designated by the numeral 15a, comprises a substantially U-shaped member or yoke, which is preferably constructed of metal so that the sides 15b ywill exert a tension toward each other and frictionally contact with both the stationary and pivoted jaw, when the sleeve is arranged in operative position. The arms 15b are provided adjacent their free edges with approximately centrally disposed alining openings through which pass the stems of headed pivots,v 50, which hingedly sustain a top or plate 51 between the arms of the'sleeve and in contacting relation with the outer face of the jaw 9. The plate 51, it will be noted, will tilt upon its pivots and lie flat upon the outer face of the jaw 9, when the sleeve is slid to force the said aw into tight engagement with an article between the j aws, and the opposite lower corners of the plate are beveled or rounded so that no resistance will be offered when the sleeve is moved over the outer declivous surface 14 of the tail 12 of the jaw 9 or the shoulders or transverse walls provided by the depression C.

From the above description, taken in connection with the accompanying drawing, the simplicity of the device as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such inventions appertain without further detailed description.

I-Iaving thus described the invention, what we claim is:
